Described from a male sj^ecimen presented to the Bri- 

 tish Museum by Dr. Dieffenbach, measuring from the fore- 

 head to the end of the abdomen, exclusive of appendages, 

 two inches ; from the end of the tarsus of hind leg to the 

 end of antennae stretched out it measures at least ISj 

 inches. Dr. Andrew Sinclair has presented a specimen of 

 a female, which, with its hind legs and antennae extended 

 is at least 14 inches long ; its head and body, exclu- 

 sive of appendages, being ^^ inches, its ovipositor is rather 

 more than an inch long, is slightly bent upwards and com- 

 pressed through the greater part of its length, the two 

 blades being somewhat angular at the base ; nearly the
